Answer:
X= 5, -2
Step-by-step explanation:
This would be the answer if you are looking to "solve"
First factor out 2
2(x^4 - y^4)
Rewrite it as ((x^2)^2) and ((y^2)^2)
Then you get..
2 ((x^2)^2) - (y^2)^2))
Now both terms are perfect squares, factor using the difference of squares formula, a^2 + b^2 = (a+b)(a-b)
a= x^2 and b= y^2
2((x^2 + y^2)(x+y)(x-y))
clean it up!
2(x^2 + y^2)(x+y)(x-y)
Answer:
h=65 ans
Step-by-step explanation:
h=16(t-1\4)(t-1\4)+49
h=16+49
h=65 ans
Answer: the lowest commission is $163.96
Step-by-step explanation:
Let x represent the lowest monthly commission that a salesman earned.
Let y represent the highest monthly commission that a salesman earned.
The lowest monthly commission that a salesman earned was only 1/5 more than 1/4 as high as the highest commission he earned. This means that
x = y/4 + 1/5 - - - - - - - - 1
The highest and lowest commissions when added together equal $819. This means that
x + y = 819
x = 819 - y - - - - - - -2
Substituting equation 2 into 1, it becomes
819 - y = y/4 + 1/5
Multiplying through by 20, it becomes
16380 - 20y = 5y + 4
25y = 16380 - 4 = 16376
y = 16376/25 = 655.04
x = 819 - 655.04 = 163.96
